How to Choose a Basement Waterproofing Contractor in Ohio
Updated · Holdfast editorial · 2 min read
What should be on your checklist?
- Proof of insurance
- Written scope and price
- Transferable warranty
- Permits where required
- Local references
What are the red flags?
- Same-day pressure pricing
- Sealing paint as the whole fix
- No written warranty
What questions should you ask?
- Where do you think the water is coming from?
- What would you do first, and why?
- Is the warranty transferable, and what does it exclude?
- Do you pull permits for excavation or structural work?
- Can I see proof of liability insurance?
Which warranty details should you compare?
Compare the length of coverage, whether it covers labor and materials, whether it transfers to a buyer and at what cost, what maintenance you're required to do (such as testing the sump pump), and what's excluded. A long warranty with broad exclusions can be worth less than a shorter one that clearly covers future seepage.
Call a professional if
- Water coming through a crack that's widening or displaced
- Walls bowing inward or cracks in a stair-step pattern
- Standing water near electrical panels or appliances
